In SUPERMAN: EARTH ONE, VOL. 2, a young Clark Kent, while slightly more settled in Metropolis from when we last left him, is still struggling to find his footing both as a reporter and as his superhero alter-ego, Superman. When a powerful new villain threatens Metropolis and drains him of all his powers, Superman will learn for the first time what it means to be vulnerable -- in other words, what it means to be truly human.
